IMPRGVEMENT IN SCISSORS-SHARPENER.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern:

`Be it known that I, NATHANIEL BELCHER, of Boston,in the county ofSuiolk and State of Massachusetts, have invented an Improved scissorssharpener, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing making part of this specification, in which- Figure l is a perspective view of my improved scissors-Sharpener. Y

Figure 2 is a longitudinal vertical section through the center of the same.

My invention consists in making the file of a' scissors-Sharpener adjustable, so that a new portion may be brought into use as soon as that previously used becomes worn out, thus enabling me to produce an 'instrument which can be kept in a serviceable condition for a great length of time.

To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawing- A is a block of hard wood or other suitable material, a portion of the upper side of which is cutaway, so as to form a gauge, b, for the blade of the scissors to rest against as itsedge is moved back and forth over the surface of a le or Sharpener. B, which fits into a slit, c, in the block-A, the inclination of the gauge b corresponding -to that of the beveled edge of the blade to be sharpened.

On the under side of the tile B is a dovetailed pro jection, d, which slides in a groove, e,o` corresponding form, in the block A, and longitudinally through this projection cl passes a screw, f, which is held in place within theblock by a pin, 3, and is provided with a head, g, by turning which the file may be moved in either direction," so as to bring a new portion of its surface into use as soon as that previously used has become worn out. The whole surface of the le may thus be utilized, and the instrument keptin servicable condition for a great length of time.-

The above-described scissors-Sharpener is of simple construction, not liable to get out ot' order, and may be furnished at a very moderate cost.

Claim..

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

The adjustable file or Sharpener B, in combination with the block A and gauge b, operating substantially in the manner and for the purpose set forth.

' fitness my hand this 27th day ot April, A. D.

NATHANIEL BELOHER.
